Otherworld Girl Development Guide

In the sky, a large quadcopter equipped with a photonic chip computer serves as an information node in this combat network, responsible for issuing commands to drones within the cellular network.

The main combat force in confined areas consists of teacup drones. These small drones, about the size of a teacup, have coaxial counter-rotating propellers on top and warheads on the bottom. They fly into confined areas, where their internal infrared sensing system automatically controls them to fly towards a heat source and then self-destruct with a bang.

What the sergeants have to do is go into complex environments that drones can't handle and wipe out the underground ratmen.

As the attack date drew closer, more and more drones were being transported from Shangqiu to the underground ruins, and some research institutes simply sent their research projects directly over.

For example, a hundred bipedal drones, with their slender bodies somewhat similar to the Trade Federation combat robots in Star Wars, make one wonder if their combat capabilities are the same as in the movies.

The stainless steel body is very cheap to manufacture, costing less than three thousand yuan... The most expensive parts are the radio frequency crystal, superconducting battery, and optoelectronic equipment.

According to the research institute, this robot was originally intended for civilian use, to serve as a "laborer." The reason it was designed this way was simply because they were too lazy to think about its appearance, and since there wouldn't be any infringement issues on Mingrui Star's end anyway.

"All departments and units, the rat extermination operation countdown is 45 minutes..."

In the ground command center, the commander in charge of overall coordination spoke in a deep voice.

Buzzing... The underground wireless power transmission device began to operate at full capacity, radiating energy in all directions, and the wireless charging modules on the surrounding drones began to charge.

The folded bipedal drones quickly unfolded, stood up, and, holding flashlights, marched forward in a very straightforward formation under the command of the cellular network.

In fact, these drones are truly cannon fodder... The General Staff expects that they will be lucky if they can eliminate the same number of ratmen.

After all, they're cheap weapons costing 3000 yuan each, so you can't expect too much from them. They really wear their cheapness on their sleeves. The main aiming method is still the laser designator on the laser weapon... The system AI just moves forward, aims, and fires, repeating this process over and over again.

Clap clap... One hundred mechs formed a recessed exploration formation, with quadrupedal mechs behind them, their photoelectric towers constantly scanning the terrain ahead.

The Mountain Cat Assault Vehicle serves as a reconnaissance unit, quickly advancing to scout the location of the ratmen.

In the sky beneath the ruins, large gyroplanes hovered in the air, serving as nodes in the Hive Network and transmitting commands from the ground, while the healers responsible for charging remained behind them.

Their wireless charging devices would interfere with communications, so they stayed behind the lines.

The sergeants remained in the safest rear area, awaiting initial orders from their superiors.

Tick-tock... Time ticked by, and forty-five minutes passed quickly...

"I command, begin the rat extermination operation!"

The command was transmitted underground in the blink of an eye via fiber optic cable, and the drone army immediately began to move!

Under the control of the cellular network, each drone received instructions. Ten bipedal drones formed an attack cluster and advanced in a loose formation, while quadrupedal drones followed behind the bipedal drones as the assault units.

Between formations, tracked drones are used as infantry fighting vehicles...

Soon, the ratmen emerged from the sewers in the underground ruins and hid in the dark corners, preparing to ambush these hairless creatures.

"Iron lump! DEA! DEA!"

In the sky, the drone's photoelectric sensor captured the location of these rat-men and sent it to the Hive Network. After being processed by the supercomputer, the instructions were sent to the corresponding units.

More than a dozen tracked drones came to a stop. Driven by hydraulic devices, the square launch pads, resembling rocket pods, slowly rose. Then, with the whirring of high-pressure air, one teacup-sized drone after another was launched forward.

After these teacup drones were deployed, their relatively heavy warheads quickly corrected their flight attitude, and the propellers started spinning, propelling the drones toward concealed corners.

The mosquito-like sound made the rats uneasy...

Soon, the mice discovered these strange things that could fly in the sky, and at the same time, the teacup drone spotted the cute mice and immediately crashed into them.

Boom! Boom! Boom!

In the dark corner, bursts of fire erupted as the warhead exploded, shrapnel and steel balls raining down on the ratmen, turning them into sieves.

Death has come to collect the rats...

Chapter 303 F2A (4/13)

Swish!Swish!Swish!

The B1 replica robot marched in orderly steps, calmly raising its small laser gun as it faced the charging subterranean ratmen.

Fire...

?——————?

?——————?

High-energy laser beams pierced through space, striking the rat-men charging towards them. The rats were instantly roasted to near-cooked perfection, collapsing to the ground groaning in pain, their fur burned and ashes rising from their blister-covered bodies.

If being hit by a B1 laser gun might elicit a cry of pain, being struck by a high-powered laser from a quadrupedal mech, with the high-energy laser piercing through the body and burning a large section of it black from the inside out, would leave one collapsing to the ground without a sound...

"Iron lump! DEA! DEA!"

Countless strangely shaped rats emerged from the cracks in the ground and, under the command of some advanced ratmen, formed attack formations. Then, with haphazard steps, they charged towards the B1 robots, wielding melee weapons.

From the perspective of the underground ratmen, the enemy was just a small group, and they could be wiped out by attacking from all sides!

The B1 Monkey Board Robot stopped in its tracks according to its programmed artificial intelligence, deployed its battle formation, and launched an attack on the approaching ratmen with its lasers.

BIU! BIU! BIU!

The laser beams kept hitting the ratmen, and one by one they collapsed to the ground from the burns, gasping for breath... soon they were exhaling more than they were inhaling.

The quadruped mechs behind them stopped; the high-energy lasers on their bodies were slightly taller than the stupid robot in front.

The photoelectric ball swiftly swept past the rat-men...

[IFF is not responding...]

[Weapon Selection...]

[Banded laser...]

Karanz's big eyes lit up instantly as the superconducting battery began to power the laser beam.

Swish!

A beam of laser light, far exceeding the power of the flashlight in B1's hand, shone into the swarm of mice and immediately began to sweep horizontally... From the air, the beams of laser light fired by the quadruped robots looked like thermal weapons fired by "colossi" sweeping over small dogs. One by one, the "cute" mice died peacefully before they could even remember their lives.

I, the little mouse... passed away peacefully.

Soon, the morale of the underground ratmen plummeted, and they were on the verge of collapse. If it weren't for some special higher rats maintaining order among the ratmen, they would probably have collapsed by now.

The ratmen did attempt a sneak attack, but countless teacup-shaped drones, like fireflies, floated above the drone swarm. The LED lights on these drones flashed intermittently, making them particularly noticeable in the pitch-black underground ruins.

The quadcopter drones in the sky are constantly monitoring the battlefield. Once they discover that these unscrupulous rats are about to launch a sneak attack, they will send them a "QN202" or a "teacup".

The drone swarm passed by almost entirely in F2A formations, leaving the ground littered with rat-men burned to death by lasers, which fully explains the ridiculously high reproductive rate of rats.

After an hour of fighting, the drones' battery was down to 60%, and the swarm stopped advancing and took up defensive positions...

Immediately afterwards, the nurse began to move closer to the front line and charge the drones wirelessly.

The rabbit's chosen tactic was to proceed steadily and gradually shrink the ratmen's living area. Drones are not humans; they need to eat and sleep. As long as the motor body is not damaged, they can theoretically continue to work.

After the drone swarm stopped advancing, the sergeant major, wearing a full-coverage exoskeleton combat suit and holding an 18.4mm military electrothermal shotgun (I've never understood why shotguns and guns are banned words; what happened?), began to clean up the battlefield.

Two Mountain Cat assault vehicles, carrying boxes, followed behind them like dogs.

Just as a ratman who hadn't died yet was about to stand up, it was hit by a slug loaded with a detonator. With a "whoosh," its entire upper body exploded into a bloody mist, and its lower body fell to the ground with a thud. The rabbit-characteristic dark green shell casing (some people always tell me that shotgun shells have red casings, please go and search "Type 09 military shotgun shell" on Baidu) fell to the ground with a thud.

During the sweep of the battlefield, the sergeant's attention was quickly drawn to the weapon in the hand of a dead ratman. Among a group of stone weapons, a futuristic-looking metal weapon was hard to miss, but before that, he gave the ratman a finishing shot.

After confirming that the mouse was completely dead, the sergeant picked up the weapon next to the mouse, packed it up, and put it into the crate of the Mountain Cat assault vehicle.

Soon, the artifacts of the ancient civilization were collected and placed in special containers. Whenever the boxes of the Mountain Cat Assault Vehicle were full, the Mountain Cat Assault Vehicle would obediently run to the winch to unload the cargo, and then replace it with a new container and return to the sergeants' side.

"No hair..."

Before the ratman could finish speaking, a shot blew its rat head off.

In the ground command center, the rabbit finally experienced what it meant to be a dimensional reduction strike... It really was like playing a game; with just a click of the touchscreen, the swarm would automatically adjust its attack direction and push forward all the way.

So far, we've only lost a few B1 monkey-type robots, and that was because one of those idiotic robots accidentally fell into a ditch and couldn't get out...

"Has the data been recorded?"

"It's all been recorded."

The commander nodded. These data were valuable for reference, but only for reference... After all, the first thing to do in a war on Earth is electronic warfare, and under various electromagnetic interferences, the combat effectiveness of drones is greatly reduced.

Unless it's an unmanned combat unit like the Azure Phoenix, which is built with money, combat robots like the B1 Monkey Board... are just free kills on the battlefield.

Next to the winch, chemical defense soldiers took out the boxes that were brought up and then disinfected them.

Disinfectant was washing over the objects left behind by the ancient civilization in the box. As for whether they would be damaged... the more advanced the civilization, the more durable and resilient the objects were. At least Wang Shu was not damaged despite being subjected to all sorts of abuse by the rat people, which shows how advanced the manufacturing technology of the ancient civilization was.

After thoroughly disinfecting the items in the boxes, the experts began to categorize the "trophies" and pack them into boxes for storage.

After affixing barcodes, the assistants loaded these ancient artifacts into the upgraded Z-20 helicopter, "Pelican," on the tarmac.

Soon, the helicopter, fully loaded with artifacts from ancient civilizations, took off and flew rapidly towards Shangqiu, where these artifacts would be further studied.

Chapter 304 Inductive Gravitational Field Driven Device

The battle in the underground ruins is in full swing, with swarms of drones carrying out a comprehensive extermination operation against the ratmen. In particular, the appearance of palm-sized quadruped drones has instilled fear in the ratmen.

Once released, the robots burrow into tiny crevices and venture deep into the underground ruins, where they then become hunters of the ratmen.

They lurk in various corners where the ratmen are not paying attention, waiting for the ratmen around them to arrive.

When the ratmen get close, the self-destruct robot's safety will be released, and it will use sound to find the approaching enemy, and may even move towards the ratmen on its own.

Then, when the rats aren't looking, it leaps up like a bouncing bead hunting its prey and self-destructs next to the ratman.

The internal explosive charge is roughly equivalent to a non-bear-shaped defensive grenade. The pre-fabricated shrapnel at the tail of the self-destructing robot and nearly a hundred steel balls, each about 2mm in size, are scattered out, creating a purgatory of steel and flames.

Simply put, it's a self-propelled mine... It has two attack methods: one is self-destruction when its power is about to run out, and the other is offensive self-destruction.

On the ground, swarms of drones were conducting brutal F2A attacks, while underground, there were self-propelled mines... Under repeated torment, the ratmen finally remembered the fear of being dominated by the terrifying upright apes.

A few days later, the ground command clearly found that the ratmen were no longer able to launch an effective large-scale counterattack, and the listening devices could hear the sound of self-propelled mines exploding underground almost every moment.

However, this still cannot guarantee the effective eradication of the rats, especially after discovering that rats cannibalize each other. This will undoubtedly turn the battle into a protracted war, but a protracted war... no one understands a protracted war better than me!

Soon... for unarmored targets like the ratmen, a very inhumane, but very rat-like, warhead was replaced with a conventional warhead.

They developed a liquefied crystal propellant that had been underutilized for a long time. This kind of thing is too inhumane. The Chinese only kept it as a technological reserve, but now it is being used on the battlefield.

The mice discovered that the latest gadgets couldn't kill them instantly, and before they could even rejoice, a nightmare struck!

Once this type of ammunition enters the rat-man's body, the crystalline protrusions circulate with the bloodstream, acting like invisible scrapers to attack the body from within.

At first, the ratman didn't feel much pain when hit by the liquefied crystal bullets, just a lot of pain. But soon it realized it wasn't just pain; a throbbing pain spread throughout its entire body, from the inside out. The pain caused the ratman to tear its skin with its claws, but even that couldn't remove the wandering crystalline clusters within its body...
